Port D shares its pins with CMP3+/PD0, CMP1–/PD1 and
CMP12+/PD2, CMP2–/PD3 of the comparators. The output of the
comparators is a status bit internal to the MCU. This circuitry is used for
the comparison of analog signals, with a digital output. The comparator
circuitry may be powered up by setting the CEN1, CEN2, and the CEN3
bits in the comparator control/status register. This register is located at
$0022 and is cleared by reset. The state of the comparator output bit
upon RESET is logic 0. For further electrical information see
